Thank you! Now I can see printf works, but.....

When I “Run” the code, the discovery board just die as there is no error information.
When I “Debug” the code, it can run well for a while and I can see the printf information. However, I will see the following information after a while...

No source available for “_swiwrite() at 0x8000516”
